We finalized with PSD Nürnberg about 3 weeks ago after I had inquired there again regarding the modalities for drawing the loan.
Total requirement was 478k€.
We financed 350k€ at 1.46% with a 15-year fixed interest period and the possibility to change the installment twice.
25-year full repayment was too fixed for us.. (e.g. to be able to reduce it if a child arrives etc)
It would have been at 1.76%.
By far the best offer.
